Question

Does anyone know the answer ?

Answer 1

x = 24

Explanation:

You're going to equal these angles to 180.

(x-17) degrees has a consecutive exterior angle. That angle happens to be vertical to the one you're trying to find which means they would have the same answer.

x - 17 + 7x + 5 = 180

8x - 12 = 180

8x = 192

x = 24

Answer 2

We have:

(x - 17)⁰ + (7x + 5)⁰ = 180⁰

x - 17 + 7x + 5 = 180⁰

8x - 12 = 180

8x = 180 + 12 = 192

x = 192/8 = 24

Answer: 24

Ok done. Thank to me :>
